Description
Technical field
The present invention relates to cooling tower applicating energy-saving field, particularly a kind of multi-functional cooling tower application process and system that utilizes natural cooling source and water-cooled machinery low-temperature receiver respectively that provide for the user that all need freeze throughout the year.
Background technology
Cooling tower is a kind of according to evaporation of water heat absorption principle, utilize air to leave with the contact (directly or indirectly) of water that industry is gone up or refrigeration air-conditioner in the heat abstractor that moves with the assurance system of the used heat that produces.Be mainly used in fields such as air conditioner cooling system, freezer, plastic cement chemical industry, generating, steam turbine, aluminium section bar processing, air compressor machine, industry water cooling.
The cooling tower of using at present mainly contains two kinds:
A kind of is the open type cooling tower, and its cooling principle is, through with recirculated water with spray pattern; Spray on the filler of glass fibre,, reach heat exchange through contacting of water and air; Drive air-flow circulation in the tower by blower fan again, will take out of with the thermal current after the water heat exchange, thereby reach cooling.Open type cooling tower initial cost is few, and maintenance point is many.Because of nothing carries tank, need boiling water pond at the bottom of tower during use, floor space increases, be accompanied by the pond to offer water pump bigger with the electric power investment, the operation cost that water consumes and power consumption causes is higher.The open type cooling tower water is directly exposed in the air, causes water quality to degenerate easily, is applicable to that to water quality requirement be not very high place.
A kind of is closed cooling tower, is made up of an internal circulation system (circulation) and an external circulating system (water-spray system).Its cooling principle is: interior circulation with dock with cool equipment, constitute an enclosed circulatory system (circulatory mediator is a soft water), for cold being provided, will use the heat in the cool equipment to discharge with cool equipment; Outer circulation contains it and carries tank in cooling tower, lowers the temperature for cooling tower itself, and outer circulation does not contact with interior recirculated water, just carries out the heat exchange heat radiation through the copper tube surface cooler in the cooling tower, through automatic control, the operation of motor is set according to water temperature.The closed cooling tower initial cost is higher, and maintenance point is few.The water quality of its recirculated water does not receive ectocine, is applicable to the cycle water requirement than higher occasion.
Summary of the invention
A kind of multi-functional cooling tower application process and system that utilizes natural cooling source and water-cooled machinery low-temperature receiver respectively that provide for the user that all need freeze throughout the year provided by the invention; According to providing the situation of natural cooling source to select low-temperature receiver neatly with cool equipment import and export temperature and natural environment; Make a cover closed cooling tower have closed cooling tower and the effect of open type cooling tower concurrently, saved purchasing of an other cover open type cooling tower.
The technical solution adopted for the present invention to solve the technical problems is:
According to an aspect of the present invention; A kind of multi-functional cooling tower application system is provided; Natural cooling source and/or water-cooled machinery low-temperature receiver can be provided; Comprise that with cool equipment, closed cooling tower, steady of system press and water replanishing device, circulating pump, handpiece Water Chilling Units, spray pump the circulating water outer circulation water system of unifying in said closed cooling tower comprises is characterized in that:
Said application system also comprises triple valve I, triple valve II, triple valve III, and each triple valve includes inlet, first outlet and second outlet, and said inlet is selected a ground and is communicated with said first outlet, second outlet;
Said internal circulation system, steady of system press and water replanishing device with cool equipment, triple valve I, closed cooling tower, circulating pump, triple valve II, handpiece Water Chilling Units are communicated with through pipeline successively, constitute first loop; Saidly be communicated with the inlet of cool equipment with triple valve I, the internal circulation system of closed cooling tower is communicated with first outlet of triple valve I, and steady of system press and water replanishing device export with second of triple valve I and be communicated with; Said circulating pump is communicated with the inlet of triple valve II, and handpiece Water Chilling Units is communicated with first outlet of triple valve II, is communicated with second outlet of triple valve II through chilled water bypass connecting pipe road with cool equipment;
The external circulating system of said handpiece Water Chilling Units, triple valve III, spray pump, closed cooling tower is communicated with through pipeline successively, constitutes second loop; Said spray pump is communicated with the inlet of triple valve III, and handpiece Water Chilling Units is communicated with first outlet of triple valve III, and the external circulating system of closed cooling tower is communicated with second outlet of triple valve III through cooling water bypass connecting pipe road.
Preferably, the user for freezing throughout the year makes full use of natural cooling source.Said multi-functional cooling tower application system is according to the inlet temperature with cool equipment; It is the supply water temperature of water system; Reach the outlet temperature with cool equipment, i.e. the return water temperature of water system, and natural environment can provide the situation of natural cooling source; One be communicated with to decide and take from closed cooling tower with the low-temperature receiver of cool equipment and still take from handpiece Water Chilling Units through selecting of triple valve I, or provide jointly by closed cooling tower and handpiece Water Chilling Units.
When the supply water temperature of the interior circulation of closed cooling tower can satisfy with the requirement of cool equipment to the low-temperature receiver supply water temperature, take from closed cooling tower with the low-temperature receiver of cool equipment, utilize natural cooling source fully, the inlet of triple valve I is communicated with its first outlet; The inlet of triple valve II is communicated with its second outlet, and the pressure drop that the low-temperature receiver medium of discharging when circulating pump is producing when flowing through the evaporimeter of handpiece Water Chilling Units is less and in tolerance interval the time, and the inlet of triple valve II also can first export and be communicated with it; Simultaneously, the inlet of triple valve III is communicated with its second outlet, and the pressure drop that in the shower water of spray pump ejection is being flowed through the condenser of handpiece Water Chilling Units, is producing is less and in tolerance interval the time, and the inlet of triple valve III also can first export and be communicated with it.The equipment that this moment, whole system started has: use cool equipment, three triple valves, closed cooling tower, steady of system press and water replanishing device, circulating pump, spray pump.
